How to prevent Ubuntu from switching default audio output device to Analog Output when docked? [duplicate]
I have 19.04 on a Lenovo ThinkPad T580. When my laptop is not docked, default audio output device is "Speakers - built-in". But when I put my laptop in a docking station, it changes default audio output device to "Analog Output - ThinkPad Dock USB Audio".
I don't have any speakers connected to my dock, so I would like to continue to have audio out of the built-in speakers. Of course, I can just change it back manually every time I dock my computer, but it would be much nicer, if it just stopped changing default audio output device whenever I docked my computer.
Any ideas how to accomplish this?
I found a solution to this.
- Open this file in an editor
/etc/pulse/default.pa - Find and comment out the line containing this
load-module module-switch-on-connect - Then, restart pulseaudio with
pulseaudio -k
